Which AWS service or tool will meet this requirement?
AWS CLI
Amazon Elastic Container Service (Amazon ECS)
AWS Cloud9
AWS Virtual Private Network (AWS VPN)
Explanations:
The AWS CLI (Command Line Interface) provides a unified tool to interact with various AWS services using commands.
Amazon ECS is a service for running containerized applications and does not provide a unified method to interact with AWS services.
AWS Cloud9 is an integrated development environment (IDE) that allows coding and debugging, but it is not specifically a unified tool for interacting with AWS services.
AWS VPN is a service for establishing secure connections between on-premises networks and AWS, not a tool for interacting with AWS services.
